Ball head milling cutter for high-temperature alloy milling

Abstract

The invention discloses a ball head milling cutter for high-temperature alloy milling. The ball head milling cutter for high-temperature alloy milling comprises a tool bit comprising a first cutting edge and a second cutting edge, and further comprises a front tool face, a first rear tool face and a second rear tool face which are connected with the cutting edges; the first rear tool face is a surface with an inclined grain structure; and a hook-shaped chip containing groove is formed by the front tool face and a groove face. The problem that high-temperature alloy materials are difficult to machine is the difficult point in the current manufacturing industry, the problems that the cutting temperature is high, cutting force is large, abrasion of a tool is severe, and the machining precision and the machining surface quality do not meet the requirements exist in the cutting process, and through a series of innovative design, the ball head milling cutter for high-temperature alloy milling has the advantages of reducing the cutting temperature and cutting force, resisting abrasion, improving the machining surface quality, prolonging the service life of the tool and being good in cutting performance.

Description

technical field [0001] The invention relates to a cutting tool in the field of mechanical processing, in particular to a blade-type special milling cutter for high-temperature alloy milling. Background technique [0002] Superalloys have good properties such as thermal fatigue, thermal stability, and thermal strength. They can withstand complex stress and work normally in high-temperature environments. They are widely used in the aviation manufacturing industry. Difficult processing of superalloy materials is a difficult point in the current manufacturing industry. Cutting In the process, there are problems such as high cutting temperature, high cutting force, serious tool wear, machining accuracy and surface quality that do not meet the requirements. The flank of the traditional blade type ball end milling cutter is a continuous plane. The surface friction of the workpiece is large, and a large amount of cutting heat is generated in the contact area between the cutting edge...

[0002] Superalloys have good properties such as thermal fatigue, thermal stability, and thermal strength. They can withstand complex stress and work normally in high-temperature environments. They are widely used in the aviation manufacturing industry. Difficult processing of superalloy materials is a difficult point in the current manufacturing industry. Cutting In the process, there are problems such as high cutting temperature, high cutting force, serious tool wear, machining accuracy and machined surface quality that do not meet the requirements. The flank of the traditional blade type ball end milling cutter is a continuous plane. The surface friction of the workpiece is large, and a large amount of cutting heat is generated in the contact area between the cutting edge and the flank face and the workpiece, and it is difficult to spread. Under the action of high temperature and high pressure, the cutting edge and the flank face are severely worn, which directly affects the surface quality of the workpiece and the service life of the tool.
